I got a new bluetooth headset which has a micro usb charger. When my phone was completely drained, I tried plugging it into this charger. The "Battery Charging" thing came on screen, then immediately went away and said something like "Charger Disconnected" before going black. This repeated a few times. So I'm guessing that the amount of current supplied by that charger is lower than the amount necessary to even maintain that powered-off "charging" screen. So yeah, not all micro-usb chargers are equal.
